Intelligent Self-Cleaning and Protective Nano-Coating Solution for Wind Power Equipment

Aug 07,2025

1. Industry Pain Points
Wind power equipment is widely distributed, with some located in remote areas or harsh environments. The surfaces of the equipment accumulate dust, dirt, bird droppings, and other pollutants, which not only affect the appearance but also negatively impact the performance and service life of the equipment. For example, the accumulation of pollutants on the nacelle and tower surfaces increases the equipment's weight and accelerates corrosion; pollutants on electrical equipment surfaces may reduce insulation performance, causing short circuits and other faults. Traditional cleaning methods rely on manual labor or machinery, which are costly, inefficient, and limited by environmental conditions, making it difficult to meet the cleaning and protection needs of large-scale wind power equipment. Additionally, frequent cleaning may damage the equipment surfaces, further shortening their service life.
2. Hisense Meike Solution
Hisense Meike has launched an intelligent self-cleaning and protective nano-coating that provides efficient and convenient protection and cleaning solutions for wind power equipment. This coating is based on advanced nanotechnology and features a unique microstructure and properties. Its superhydrophobic and superoleophobic characteristics make it difficult for pollutants to adhere to the equipment surface; under rain or wind, pollutants quickly slide off, achieving a self-cleaning function. Meanwhile, the coating offers excellent corrosion resistance, weather resistance, and insulation performance, effectively protecting the equipment from environmental erosion, enhancing insulation, and ensuring safe and stable operation. Additionally, Hisense Meike equips this solution with an intelligent monitoring system that continuously monitors the coating status and pollutant adhesion on the equipment surface, automatically adjusting cleaning and protection strategies based on monitoring data to realize intelligent operation and maintenance management.
3. Implementation Steps
Equipment Survey and Planning: Conduct a detailed survey of various wind power equipment within the wind farm, including equipment types, quantities, distribution locations, and operating environments. Based on the survey results, develop a comprehensive construction plan, determining the construction sequence, schedule, and required materials and personnel allocation.
Surface Treatment: Before construction, pre-treat the equipment surfaces by using appropriate cleaning methods to remove surface oil, dust, rust, and other impurities, ensuring the surface is clean and dry. For special equipment or parts, such as electrical equipment, special protective measures must be taken to prevent damage during cleaning. After treatment, adjust the surface roughness to improve coating adhesion.
Coating Application: Select suitable coating application methods for different types of equipment and parts. For large flat equipment, such as towers and nacelle shells, spraying can be used with professional spraying equipment to ensure uniform coating coverage; for complex-shaped or small equipment, such as electrical components and sensors, brushing or dipping methods can be used to ensure coating quality. During application, strictly control coating thickness and environmental conditions according to product instructions to ensure optimal coating performance.
Installation and Commissioning of Intelligent Monitoring System: Install intelligent monitoring sensors on the equipment surface, connect data transmission lines and control terminals, and complete the installation of the intelligent monitoring system. After installation, conduct comprehensive commissioning to ensure sensors accurately monitor the coating status and pollutant adhesion on the equipment surface, data transmission is stable and reliable, and the control terminal can normally receive and process data and issue commands according to preset strategies.
Training and Delivery: After construction is completed, train the wind farm operation and maintenance personnel to familiarize them with the nano-coating's performance characteristics, maintenance methods, and the operation of the intelligent monitoring system. After training, formally deliver the equipment to the customer and provide comprehensive after-sales services, including regular follow-ups, technical support, and coating maintenance.
4. Expected Effects
Achieve Equipment Self-Cleaning: Effectively reduce pollutant adhesion on equipment surfaces, utilizing natural rain and wind to achieve self-cleaning, thereby reducing the frequency and cost of manual cleaning. It is expected to reduce cleaning frequency by more than 50%, significantly saving labor and material resources.
Extend Equipment Service Life: The coating's corrosion resistance and weather resistance effectively protect equipment from environmental erosion, extending service life. It is expected to extend the overall service life by more than 5 years, reducing replacement costs and improving the investment benefits of wind power projects.
Improve Equipment Operational Stability: By maintaining clean surfaces and good insulation performance, the probability of faults caused by pollutant accumulation and insulation degradation is reduced, enhancing operational stability and reliability. It is expected to lower the failure rate, ensuring continuous and stable power generation at the wind farm.
Intelligent Operation and Maintenance Management: The intelligent monitoring system provides real-time equipment status data to support operation and maintenance decisions, enabling intelligent management. Based on monitoring data, equipment issues can be promptly identified and addressed, improving maintenance efficiency and reducing risks.
